There are some reason that will take you to choose to use a Data Lake as solution for your Data Operations. The most importants are:

• Increase operational efficiency
• Make data available faster
• Lower transaction cost
• Offload capacity from databases and data warehouse

The common work of the databases is that the storage and the processing is tied together making less flexible to scale storage without processing. In the other hands, the data lake is a centralized repository to secure store structured and unstructured data, with no scaling restrictions. Store the data without having to think about its structure its really important if you think about the modularization of the process. Even the data process.
